It’s Solarthon season! What does that mean? As some of you know, that means I’ve signed up to help install solar panels for low-income families with GRID Alternatives. And I’m asking for your help to sponsor me.

Why is this important to me? Because together, we can help bring clean, affordable energy to those who need it the most. But wait, that’s not all!

Through the simple act of installing solar electric systems for low-income families, GRID Alternatives accomplishes so much more:

An average GRID solar installation saves a family $28,000 over its lifetime and prevents 95 tons of greenhouse gas emissions.

GRID has installed solar for over 3,000 low-income families, saving those families $92 million and preventing nearly 290,000 tons of greenhouse gas emissions.

This helps improve the environment, the economy, public health, national security, and global politics — which helps you, too!

But don’t take my word for it: See what my friends have to say in this video. Be sure to watch till the end to see what Luna the Cat thinks of solar power!

So, want to help yourself while helping others?

Just click here to sponsor me — any amount helps, even a few dollars:

No pressure at all. But if you can give, I greatly appreciate it!

Thanks so much for your support, and thanks again to all of you who’ve sponsored me for previous Solarthons!

This infographic, from LearnStuff.com, gives a good graphic representation of the extent of climate change and its effects — in case you’re not convinced already! Reality is catching up to film depictions of what was expected to happen far in the future. Seeing Superstorm Sandy flood parts of New York City made me feel like I was watching The Age of Stupid or Earth 2100 — except it was happening now, not in some distant future.

As the infographic shows, if we continue on our current trajectory, things will only get worse by 2050. And given the fact that many predictions have turned out to be too conservative, 2050 might be an optimistic target.

Depressed? While this can be depressing, it can also be a call to positive action. More people are realizing climate change is real, and upon us already. So let’s choose to make a difference. You can start by sharing this infographic to help show that action is needed. Together, we can make some real changes!

Yogi Berra might have been referring to the solar industry when he said, “It’s tough to make predictions, especially about the future.” But that never stops people from trying! As we look back at the many predictions about the solar industry for 2012, it’s instructive to see how they stacked up to reality.

The beginning of the year brought a mixed bag of forecasts, as the industry looked forward to continuing growth coupled with serious risks — an oversupply of panels, diminishing subsidies in the U.S. and Europe, and a trade war with China.

Predictions for 2012 were numerous and all over the map. But some clear trends emerged.

Global predictions

We’ll see consolidation as the industry matures. One thing everyone from GigaOM to Renewable Energy World to the New York Times seemed to agree on for 2012 was that the solar industry was due for a lot of consolidation — which was only to be expected in a competitive emerging industry. This bid for survival of the fittest, many argued, would lead to a stronger industry with clear winners, those who could provide the best products at the best prices.

VERDICT: Predictions were close.

Bankruptcies and consolidations have indeed continued in 2012. But the shakeout is far from over. A Green Tech Media report released late last year predicted that another 180 solar panel makers will likely go out of business or be bought by 2015. In fact, at the end of 2012 China announced it’s encouraging consolidations and letting some of its weaker manufacturers go out of business. That’s likely a positive move on the part of China, one that will result in a stronger manufacturing industry overall. Consolidation is also expected to continue withdownstream players. And we’re seeing panel manufacturers get into the development business, either on their own or with partners — which some consider key to the future of Western solar manufacturing. We’ll watch these trends in 2013, as the industry’s evolution continues to play out.

19 – 29 GW will be installed globally, 2.8 GW in the U.S. While Energy Trend forecast only 19 GW in global installations for 2012, most others had higher expectations.HSBC predicted a flat market with 25.5 GW of global solar installations in 2012, down from 2011’s 27.4 GW, while IMS Research expected 26–29 GW of new PV capacity in 2012. A good year was expected in the U.S., with total installations forecast at 2.8 GW. CleanTechnica didn’t provide specific figures but predicted record amounts of solar installations in the U.S., for both homes and businesses.

VERDICT:Predictions were mostly off — but in a good way!

Solar installations both worldwide and in the U.S. exceeded expectations. The SEIA/GTM 2012 Q3 reportforecast 31 GW in global demand, and as more information became available IHS reported that totals reached 32 GW. For the U.S, the SEIA/GTM report forecast a total of 3.2 GW of PV installed in 2012, up from 1.9 GW in 2011.

CleanTechnica was likely not surprised that numerous stories appeared last year about well-known corporationslike IKEA, Walmart, Costco, FedEx, Kohl’s, Crayola, Apple, and Google going solar in the U.S. Schools and government agencies, including theDepartment of Defense, also increasingly found that solar made sense for them.

What does this all mean? We’re talking 70% growth in the U.S. installation market over 2011, with an expected growth rate of 14% worldwide. That’s not too shabby for an industry experiencing so many challenges.

We’ll face an oversupply of panels. An oversupply has been predicted since 2009, and last year was no exception. This wasn’t a controversial prediction, given that it was really about a continuation of an already existing situation. By the middle of 2012, Bloomberg New Energy Finance was forecasting that demand for solar will not match supply until at least 2014.

VERDICT:Predictions were spot-on.

The end of the year found us with a continued oversupply, which many feared would weaken the industry. There’s a bright spot, though, in addition to cheaper prices for installers and consumers: China’s response to the oversupply has been a decision to add 10 GW of solar generating capacity in 2013 and possibly get to 40 GW by 2015, in part to help their manufacturers. One thing to watch will be how successful they are in connecting all that solat to their grid. But in any case, the huge supply of panels has lowered the cost of solar, already resulting in more installations worldwide — that’s a good trend to keep going.

Of note was that China installed even more solar generating capacity than expected, coming in at 7 GW, more than double the 2011 figure. India’s solar industry, meanwhile, is experiencing some growing pains — that doesn’t mean that growth won’t continue, but it may have been slower than expected for 2012. Other Asian countries are adopting feed-in tariffs and other programs to accelerate solar adoption, while Latin America is still talked about in terms of potential. 2012 brought some surprises, among them Saudi Arabia — a country whose desire to make profits from importing oil rather than using it at home is leading it to invest $109 billion in solar, with the goal of generating a third of its power from solar by 2032.

While cheap panels from China have certainly fueled much of the industry’s growth, the November imposition of tariffs by the ITC happened too late in the year for many effects to be felt yet — plus some Chinese panel makers have thwarted the objectives of the tariffs by routing exports through Taiwan and other locations. Tensions mounted late last year amid rumors that Europe was also getting into the trade war action with China, but as of early this year, an EU trade war seems to be off the table. This will be one to watch in 2013. The question remains whether the industry can continue its upward trajectory without an infusion of cheap panels. But other factors will play into that, such as attempts to reduce soft costs, and additional feed-in tariffs in some areas.

The financial scene

Diminishing grants and subsidies will hurt the industry. In the U.S., the 1603 Treasury grant program was not extended into 2012, causing concerns that without this incentive, many solar projects would not happen. Meanwhile, feed-in tariffs in Europe were facing reductions, leading many to wonder about the fate of solar in Italy and Germany.

VERDICT: Predictions were off.

The expiration of the 1603 program hasn’t yet had far-reaching effects — that may be because projects qualified for the grant if panels were purchased in 2011, as some astute observers noted even early in 2012. In addition, many other factors, including the decreasing costs of solar, might mitigate this effect. That can also be said of areas where feed-in tariffs are on the decline. While feed-in tariffs have been shown to quickly boost an area’s solar industry, some countries that once strongly supported them are moving to broader adoption of other models, such as PPAs. In addition, other markets have taken up the slack for Europe, as noted above, and some countries are still introducing feed-in tariffs.

The solar market will be flat at best, with shrinking revenues likely. Oversupplies and price declines, coupled with weak economies and cuts to tariffs and subsidies in some regions, were expected to shrink revenues or keep them flat in spite of growth in megawatts installed. EnergyTrend expected no rapid growth till 2013.

VERDICT: Predictions were spot-on.

While this year brought considerable growth in terms of GW installed, revenues (system prices multiplied by total GW installed) did not fare so well. According to IHS research, revenues fell from $94 billion in 2011 to $77 billion in 2012. The good news is that they’re expected to pick up by 2014 — this will be another trend to watch.

Solar will get cheaper, helping more areas achieve grid parity. Most expectations were that prices of solar technologies would drop, and that falling prices coupled with rising electricity rates would encourage installations even where subsidies were ending. SunRun put numbers to this, predicting a 20% drop in price. And according to John Farrell of the Institute for Local Self-Reliance, solar hasalready reached grid parity in many areas, a trend that he expected to continue in 2012 and beyond.

VERDICT: Predictions were spot-on.

A report by the Lawrence Berkeley National Laboratory showed that costs of solar systems in the U.S.continued to decline in 2012. And the SEIA Solar Market Insight Report found a decline in average installed costs of 19.3% — making SunRun’s prediction quite close. While this is great news for installers and consumers, lower costs are putting pressure on manufacturers. But many analysts believe that this will help the industry in the long run — and when you look at the increases in installations worldwide, it’s hard to disagree with that.

Solar will get more expensive. Okay, this one may be an anomaly, but it just shows how hard it is to find “agreement parity” when it comes to analyzing solar. A forecast for the year in Renewable Energy World strayed from the crowd, arguing that prices have to increase to a healthy level and predicting that they would do so by the end of 2012.

VERDICT:Predictions were off.

As noted above, prices continued to fall in 2012. It will be interesting to see if 2013 brings a price increase in the U.S., as tariffs are imposed on Chinese panels. On the other hand, decreases in soft costs could offset that. Time will tell!

New financing options will become more prominent. PPAs and solar leasing options were expected to become more widespread in 2012. SunRun estimated that leases would account for about 75% of the California solar market.

VERDICT: Predictions were spot-on.

In fact, Tom Kimbis of the SEIA attributes the growth in solar installations in 2012 tofinancial innovations. And leases and PPAs, though not new in 2012, became more widespread. By March, these options already accounted for 73.4% of residential solar installations in California. For those who can’t get solar on their own roof, we’re also seeing growth in crowdfunding and impact investing options — another trend to watch in the coming year.

More jobs will be created in the solar industry. I was surprised not to see more predictions on solar jobs for 2012. But a few sources did note that there wasbound to be an upswing, not surprising since that correlates with predictions for industry growth. The 2011 National Solar Jobs Census predicted installation firms in the U.S. would add 13,000 jobs in 2012, while manufacturing and sales would account for another 9,500 jobs.

VERDICT: Predictions were close.

In spite of some layoffs last year, the Solar Foundation’sNational Solar Jobs Census 2012 reported that 119,016 Americans were employed in the solar industry as of mid-November 2012, representing an employment growth rate of 13.2% over the previous 12 months — compared to a rate of 2.3% for the overall economy. In fact, solar accounted for 1 out of every 230 jobs created in the U.S. last year.

The solar stock market will be a mixed bag, with stocks going up but solar IPOs remaining rare. GigaOM was not alone in predicting a slow year for IPOs, noting that after a rough 2011, most companies would wait to see a few successful solar IPOs before attempting it themselves. Meanwhile, some analysts expectedsolar stocks to be on the rise.

As hard as it is to make predictions, while we’re focused on making the attempt, events we never anticipated are in the works. 2012 brought a few interesting surprises — and even some of the negative events of the year bode well for the future of solar.

Americans support solar and other renewables.

In spite of a lot of negative media, Americans love solar! Astudy in May found that the average American is willing to pay 13% more a year for power to support a national clean-energy standard. And aSeptember poll of likely voters showed that 92% of Americans support developing more solar, and a majority even want the government to support solar with tax credits and other financial incentives.

A major coal company admitted climate change is real and coal is on the outs.

When even coal companies admit there’s a problem with coal, you know there’s change in the air. And that’s just what happened in 2012, when BHP Billiton announced it would retrofit one if its coal-exporting facilities against significant weather events. BHP executive Marcus Randolph even said, “In a carbon constrained world where energy coal is the biggest contributor to a carbon problem … I suspect the usage of thermal coal is going to decline. And frankly it should.”

Superstorm Sandy brought attention to climate change.

And what more evidence did we need than Sandy? For those not convinced by a coal company’s pronouncement, the images of Sandy’s devastation should serve as a wake-up call. If that’s not enough, there’s the bill. With some estimates for its costs as high as $71 billion, Sandy provides further evidence that an ounce of prevention is indeed worth a pound of cure, making solar all the more attractive. And the Solar Sandy Projectwas just one example of how solar can come to the rescue in disasters.

Looking ahead

Even in a rough year for solar, we saw significant increases in installations globally, and the U.S. industry is booming. People are realizing that solar makes economic sense — the main motivation for so many businesses and schools to be jumping on the solar bandwagon. Couple that with the public’s increasing awareness of climate change, and the climate looks good for solar.

TheEconomist, a most rational publication, goes so far as to predict that renewables, especially solar, will become the new normal. They’re expecting that trend to start taking root this year. And of all the predictions and trends, that will be the most interesting to watch. We’ll check back in a year to see how this year’s predictions fare, and to see how far along we are on the road to solar as the new normal.

From the roof of my condo complex in a sunny part of San Francisco, I can see solar panels on at least a few houses on each surrounding block.

Yet solar for our condo has eluded us. When it comes to solar, condos — with multiple owners and HOA regulations — are a tough nut to crack. I’m determined to get us solar power someday, but the jury is out on when that day will come.

While I’m interested in solar for environmental reasons, most people go solar simply to save money — which is how I’ll have to sell it at my condo. After all, most of us can’t afford solar power for altruistic reasons alone. It has to make financial sense.

Yet while more people are becoming aware of the financial benefits of solar, most still can’t participate in those benefits. That’s because 75% of us don’t own our roof or have a roof suitable for solar. My condo is just one example of the many barriers to going solar for the 75%.

That’s where Mosaic comes in. It’s part of a community power movement that’s providing more opportunities for the 75% to go solar. Community power aims to decentralize clean electricity generation and make it accessible to all. As solar and other renewables become more available and affordable, the hope is that ordinary consumers of that power will benefit, rather than big companies outside their communities.

But many community power options rely on policy changes that are slow to come. A growing number of people are tired of waiting and are taking matters into their own hands to make solar projects happen. Crowdfunding has emerged as a simple and powerful way to allow the 75% to take action by investing directly in solar. With crowdfunding, even people who can’t get solar on their own roof can participate by pooling their dollars to support solar.

Till now, most crowdfunding models have been about making donations to fund solar projects. That’s great if you’re looking for a worthy charity. And it’s true that solar benefits everyone, even if it’s not on your own roof. But what if you want to reap the benefits of solar in a more direct way? Mosaic provides that opportunity with a new model that lets people invest in solar projects and get a solid return.

Is solar is worth investing in? Take a cue from Warren Buffett, whose recent purchase of two solar plants sent stocks soaring. Of course, most of us can’t afford a whole solar plant. The good news is that now, you don’t need to be a millionaire to invest in solar. One of Mosaic’s first projects is providing investors a hefty 6.4% return, and some of them ponied up as little as $25.

That’s what’s so exciting about Mosaic. With a low barrier to entry, Mosaic is bringing solar and its benefits within the reach of regular people like you and me. For me, this means I don’t have to wait to get solar on my condo. I can invest now in Mosaic and be part of bringing solar to communities, and even get a return on my investment. Finally, I’ll have a real stake in solar. Finally, I’ll get some direct benefits, without needing to put panels on my roof. Finally, I’ll be able to do well while doing good.

Every time I hear about the sharing economy, I think it’s an idea so great it has to catch on like wildfire. What could make more sense than eschewing rampant consumerism in favor of sharing? It’s clear we need to stop buying stuff we’ll rarely use and instead move to sharing, so we can access that stuff just when we need it.

But I live in San Francisco, where I’m surrounded by like-minded people. Is the sharing economy really the next big thing that’s already happening?

The truth is, we already do a lot of sharing. Think about it this way. Have you ever bought a slice of pizza? When you did that, you didn’t pay for the whole pizza, did you? Bingo — you were sharing! Have you ever ridden a bus or subway? Again, sharing! Come to think of it, even driving your own car involves sharing — of the roads we all help pay for.

But while buying a slice of pizza or riding a subway have become so acceptable that we don’t even think of them as sharing, other similar activities just aren’t as accepted yet. Sharing taxis is a case in point: not only does sharing make it easier to get a cab when they’re scarce, but you can also save money by splitting the fare. Yet most people are reluctant to share a taxi.

Recently we’ve seen some breakthroughs to this reluctance, and last week, a panel of four prominent members of the sharing economy explored how this is happening.

Superstorm Sandy put sharing in the spotlight, at least for a while. As a panelist from Weeels described, because his company facilitates ride sharing, they were called in to help after the storm. When taxis were scarce, their service helped both drivers and riders make the best use of the few vehicles that were available.

Well, we all know that during disasters people are more likely to share and help one another. But while recessions and natural disasters help make sharing palatable, we need to get beyond that for sharing to prosper.

And that will mean changing our perspective about what’s okay to share. The idea can’t be forced on people — they have to see what’s in it for them.

The panelists contributed great examples of the benefits. In addition to Weels, there was representation from SolarCity, which sells solar leases to homeowners, making it much easier for many Americans to go solar; BrightFarms, a company that provides a kind of “produce purchase agreement” to supermarkets, ensuring that both the stores and customers will get fresh produce; and Krrb, an online peer-to-peer marketplace that differs from Craigslist in operating more like a store, with accountability to customers for the products sold there.

We’re seeing added benefits to sharing when it comes to crowdfunding, which lets people pool their resources to make all kinds of projects happen. A great example is Mosaic’s new online marketplace, which is making it possible for people to invest in community solar projects and earn solid returns.

Despite the benefits, some barriers remain — perceptions being a major one. Another is the built environment. Sharing on a large scale is far more popular in urban areas, where it’s also more of a necessity and provides more obvious benefits. It’s a challenge to promote the idea in more rural or even suburban areas, especially in a culture built on the ideas of space and individualism.

Of course, our culture is also increasingly urban, and that will help advance the sharing economy. So too will the fact that so many resources are becoming more scarce, which leads to a real need to share them.

The conclusion of this panel? At the moment, getting people to participate in the sharing economy is still a challenge. But whether or not we want it to, sharing is bound to become the norm.
